Strack & Van Til Highland

The project implemented a sophisticated CCHP system as the backbone of a power and thermal microgrid, configured with dual-mode controls for an automatic transition between grid-connected and standalone operation in the event of a power interruption. The system’s two C65 microturbines produce electricity while the exhaust is channeled to integrated heat recovery modules to provide hot water. The exhaust is also used by an 80-ton absorption chiller to provide on-site chilled water which complements the grocery stores existing heating and cooling systems. Because different environmental temperatures create different needs, the systems adapt seasonally.

During the summer months, the CHP hot water output is used by a make-up air unit to provide dehumidification, while the absorption chiller provides air conditioning to the store. In the winter, however, the CHP hot water is used to provide heating for the building reducing natural gas consumption for heating.

This project is an integral part of Strack & Van Til’s sustainability commitment to reducing greenhouse gas (GHG) emissions from waste and energy. The project was also recognized for its inspiring CHP design, winning a Midwest Clean Energy Project Award from the Midwest Cogeneration Association in 2024.
